Impacto económico, ambiental y social del negro de carbono recuperado de neumáticos fuera de uso: una mirada desde la sostenibilidad

This study analyzed the economic, environmental, and social impacts of recovered carbon black (rCB) relative to virgin carbon black (vCB) through a sustainability and circular economy lens. A qualitative documentary analysis design was employed, based on a critical review of 24 scientific sources published between 2010 and 2025. Data were processed through categorized thematic synthesis, enabling a rigorous technical comparison of the analyzed dimensions. The findings revealed that rCB implementation reduced production costs by up to 70% and avoided 2.5–2.7 tons of CO₂ emissions per ton replaced. Furthermore, its use was found to stimulate job creation and mitigate environmental liabilities associated with the accumulation of end-of-life tires (ELTs). The study concluded that rCB constituted a strategic feedstock with comprehensive viability; however, its definitive industrial market consolidation was found to be contingent upon optimizing its purity and technical performance.
